CHANGES FROM 1.4 TO 1.5, 09 July 2011
* Support xterm mouse modes 1002 and 1003.
* Change from a per-session stack of buffers to one global stack. This renders
copy-buffer useless and makes buffer-limit now a server option.
* Fix most-recently-used choice by avoiding reset the activity timer for
unattached sessions every second.
* Add a -P option to new-window and split-window to print the new window or
pane index in target form (useful to pass it into other commands).
* Handle a # at the end of a replacement string (such as status-left)
correctly.
* Support for UTF-8 mouse input (\033[1005h) which was added in xterm 262.
If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all
UTF-8 terminals. The option defaults to on if LANG etc are set in the same
manner as the utf8 option.
* Support for HP-UX.
* Accept colours of the hex form #ffffff and translate to the nearest from the
xterm(1) 256-colour set.
* Clear the non-blocking IO flag (O_NONBLOCK) on the stdio file descriptors
before closing them (fixes things like "tmux ls && cat").
* Use TMPDIR if set.
* Fix next and previous session functions to actually work.
* Support -x and -y for new-session to specify the initial size of the window
if created detached with -d.
* Make bind-key accept characters with the top-bit-set and print them as octal.
* Set $TMUX without the session when background jobs are run.
* Simplify the way jobs work and drop the persist type, so all jobs are
fire-and-forget.
* Accept tcgetattr/tcsetattr(3) failure, fixes problems with fatal() if the
terminal disappears while locked.
* Add a -P option to detach to HUP the client's parent process (usually causing
it to exit as well).
* Support passing through escape sequences to the underlying terminal by using
DCS with a "tmux;" prefix.
* Prevent tiled producing a corrupt layout when only one column is needed.
* Give each pane created in a tmux server a unique id (starting from 0), put it
in the TMUX_PANE environment variable and accept it as a target.
* Allow a start and end line to be specified for capture-pane which may be
negative to capture part of the history.
* Add -a and -s options to lsp to list all panes in the server or session
respectively. Likewise add -s to lsw.
* Change -t on display-message to be target-pane for the #[A-Z] replacements
and add -c as target-client.
* The attach-session command now prefers the most recently used unattached
session.
* Add -s option to detach-client to detach all clients attached to a session.
* Add -t to list-clients.
* Change window with mouse wheel over status line if mouse-select-window is on.
* When mode-mouse is on, automatically enter copy mode when the mouse is
dragged or the mouse wheel is used. Also exit copy mode when the mouse wheel
is scrolled off the bottom.
* Provide #h character pair for short hostname (no domain).
* Don't use strnvis(3) for the title as it breaks UTF-8.
* Use the tsl and fsl terminfo(5) capabilities to update terminal title and
automatically fill them in on terminals with the XT capability (which means
their title setting is xterm-compatible).
* Add a new option, mouse-resize-pane. When on, panes may be resized by
dragging their borders.
* Fix crash by resetting last pane on {break,swap}-pane across windows.
* Add three new copy-mode commands - select-line, copy-line, copy-end-of-line.
* Support setting the xterm clipboard when copying from copy mode using the
xterm escape sequence for the purpose (if xterm is configured to allow it).
* Support xterm(1) cursor colour change sequences through terminfo(5) Cc
(set) and Cr (reset) extensions.
* Support DECSCUSR sequence to set the cursor style with two new terminfo(5)
extensions, Cs and Csr.
* Make the command-prompt custom prompts recognize the status-left option
character pairs.
* Add a respawn-pane command.
* Add a couple of extra xterm-style keys that gnome terminal provides.
* Allow the initial context on prompts to be set with the new -I option to
command-prompt. Include the current window and session name in the prompt
when renaming and add a new key binding ($) for rename session.
* Option bell-on-alert added to trigger the terminal bell when there is an
alert.
* Change the list-keys format so that it shows the keys using actual tmux
commands which should be able to be directly copied into the config file.
* Show full targets for lsp/lsw -a.
* Make confirm-before prompt customizable with -p option like command-prompt
and add the character pairs #W and #P to the default kill-{pane,window}
prompts.
* Avoid sending data to suspended/locked clients.
* Small memory leaks in error paths plugged.
* Vi mode improvements.
